CULTVATOR.

Specification of Letters `Patent.

To all whom 'it may concern Be it known that. I, CHARLES JOHNSON, a citizen of the United States, residingat San Jose, in the county of Santa Clara and- State of California, have invented `a new and` Improved Cultivator, ofwhich the following is a full, clear, and exact description. My invention relates to an improvement i11-cultivators for the purpose of cultivating the ground in orchards and fields or in any other place wherethe ground is hard and it ,becomes necessary to break .up the saine. The objects of my invention are first', to so construct a` cultivator which `will break up the earth in a suitable manner and to the l. neness that may be required. kSecond to,

so construct a eultivator that allparts thereof can be duplicated, and one which may he operated in field, orchard,.or road and one in which the cultivator teeth are reversible. Third to `so construct a cultivator that either side inaV-` be raised or lowered to any angle required without interfering with the other side, or both sides may be raised` and 'lowered at the same time. Fourth to so cony struct a cultivator that may be drawn-.by

horses or attached to a traction engine and one that may be built in any size and strength for the work required thereof.

I attain these objects by means of the parts illustrated in the accompanying drawings, in which;

Figure 1 is a perspective View of my iinproved cultivator Fig. 2 is a plan yiew of fthe same.

In the drawings similar reference characters indicate correspondingparts in all of the views.

Referring to the drawings 1 indicates the frame or longitudinal outer har and rear end cross bar which is an integral part thereof, ylongitudinal inner bars are shown at 2, forward cross bars 3 are. shown connectedto draw bars t by bolt 5 and clevis bolt 6 and clevis 7 the outer ends of said cross bars 3 are connected to longitudinal barsi12 by bolts S by which draw hooks 9 are fastened thereto to which chains 10 are connected the outer ends of which are connecb'edfto ring 11, connected to ring 11 is hook 12 connecting with link 13, Said link connecting' with clevis 7, draw ybar 14 is here shown connecting with ring 1l on the under side of pole or tongue 15, said draw bar ex- 1 .tending forward a distance, the same being' adapted to connect with a traction engine or rammed Nov. so, 1915.l

pnlcation led July' 6, 1915. Serial No. 38,133.

any other means for drawing the cultivator, i the positlonL of pole or tongue 15 1s herebars 1S are attached to Aforward cross bars 3, pole 154 being positioned therebetween,

pole 15 to any required position, thesame saidgbarsj 18 having.;` a` plurality of holes,- jtherernl as shown at l!) wlnchare for the purpose of raising or loweringthe ends of 7o being held in place by pin 20, said pole 15 A extends backwardly resting on aXle sleeve 21, the saine being` connected thereto and turnable thereon bystrap 22, upright adjusting bars are shown attached to cross barl 24; the saine having a plurality of holes 25 therein for the purpose of adjusting the .rear end of pole 15 therebetween by pin 2G,

axley sleeye21 is fastened to draw bars 4 in any suitable manner, crank axle 27 is shown having,r its innerbearing in axle sleeve 21 and its outer bearing 2h attachedv to frame 1 by bolts 2S), on the journal ot said axle'27 is mounted wheel 30, said axle beingoperated by lever arm'l fastened thereto and adapted to turn said' axle 2T in sleeve21 and bearing said lever arni 31 engaging half circle rack 32 lwhich is fastened to lon-` gitudinal inner bar in any suitable Inan-` ner, said rack L'having a 'plurality of holes.' l

33 therethrough for the purpose'of engaging lever arm 31 byspring pin 3-1, a collar 85 is .shown attached to axle 27 and bearing against longitudinal inner bar 2, this collar is for the purpose of retaining axle 27 in v position in sleeve 2l while in operation. On the other side of traine l is crank axle 3G having its inner bearing inaxle sleeve 21 and its outer bearing 37 attached to frame 1v by bolts 238, on the journal of ysaid axle 36 is mounted Wheel 39, Said axle beingop` erated by lever arm 40 fastened thereto adapted to turn said axle 36 in sleeve'21 and bearing; 37, said lever erin 40 engaging its' half circle rack 41, the saine being fastened' to longitudinal inner bar 2 in any suitable manner, said rack having a plurality A015:2 holes shown at therethrougl'i for the'purpose of engaging lever arm 10 byspring pin 113, a collar 44 is shown attached toraXle 36 and bearing againstlongitudinal inner bar 2, this-collar is for the purpose of retaining axle 36 in position in sleeve 21'Wh1le :in operation, cultivatorteeth 45 are Iade ,ouryed at their ends and are reversible, the salne beingfastened to frame 1 and bars 4 --loy -clamps 46, braces are Vshown at,47 con- .Vnecting frame 1 with draw bars 4 by bolts 44,8, .these braces are for the purpose of tre'ngthening frame 1 with bars 4. l

-Thegperation and constructlon lof my l1m- -proved cultivator is as followsz-1t will be l'rseerifthat each axle is'operated separate and independent from each other with regard to the elevation requiredI on either side of said eultivator', orboth sides maybe operated together with'regard to the depth required of the'. teeth in the ground,'the pole or tongue "can, be adJlusted to suit different positions required, t 1e teeth are curved at both ends and are lthereby reversible and adjustable bylcla'mps; this cultivator may be made in any size required for heavy or lightwork required of the same.

l Having thus described my inventiornwhat` I claim as new,

, and desire to secure by Letters Patent, is il 1. Ina cultivator fram( of the class de` scribed the combination of outer longitudinal bars 1 forming rear end cross bar, longitudinal inner bars 2 connecting with forward end cross bars 3, longitudinall bars 4, connecting With rear end cross bar 1 and cross bars 24 and bolt 5, connecting the front ends of bars 4 with cross bars 3, means by Which;said cross bars 3 are connected to longltudinal bars 1-2, braces 47 connectlngf bars l 'with lbars 4, substantially as herein described.

' 2. IIn a cultivator consisting ofthe` tooth-' Vcarryin frame the combination of the outerA longitu inal bars 1 forming rear end cross bar longitudinal inner bars 2 connecting with forward end cross bars 3 the same connecting with longitudinal inner bars 4 by bolt 5 said bars 4 connecting With rear end bars 1, and cross bar 24, and the rear ends of the bars 2 and the axle sleeve 21 fastened to Said bars '4, arid the pole or tongue 15 secured to said axle sleeve by strap 22 and turnable on said axle sleeve and carried A,by the inner bars 4 of the frame substantially as herein described.

3. In a cultivator consisting of the tooth carrying frame the combination of the outer bars l, forming rear end cross bar longitudinal Inner bars 2--4 connecting with the cross bars 3-24, and the bolt 5, connecting the front ends ofthe bars {if-4, the axle f end cross bar longitudinal inner bars2-4,

cross .bars 3-24, and braces 47, said bars 1 and bars 4 being adapted to carry clamps 46 the same being adapted to clamp cultivator teeth 45 to said bars, an axle sleeve fastened to bars 4 in which axles 27-36 operate, a collar 35 attached to axle 27 and bearing against inner bar2 adapted to retain axle 27 in position in said sleeve, a collar 44 attached to axle 36 and bearing, against inner bar 2 adapted to retain axle 36 in positionin said sleeve, substantially as herein described. i

ln testimony whereof l hereto ailix my signature in the presence of two witnesses. CHARLES JOHNSON.
